Understanding Littermate Syndrome: Important Things To Know

We know how tempting it can be to bring home two puppies at once—after all, who wouldn’t want double the cuteness? And for many, the thought of separating littermates tugs at the heartstrings. But before you decide to bring home two puppies together, it’s important to understand the unique challenges that can come with raising littermates.

At Stokeshire, we want every puppy to thrive in their forever home, which is why we encourage thoughtful decision-making when it comes to adding a new furry family member. Raising two puppies is possible, but it takes extra time, effort, and structure. Here’s what you need to know about littermate syndrome, how to prevent it, and what to do if you already have two puppies at home.

What Is Littermate Syndrome?

Littermate syndrome occurs when two puppies—often from the same litter but sometimes just of the same age—form an intense bond with each other that interferes with their ability to develop as well-rounded, independent dogs. Puppies experiencing littermate syndrome may struggle with training, socialization, and separation, leading to long-term behavioral challenges.

It’s a common misconception that all littermates will suffer from this condition, but without proper structure and training, many puppies raised together do become overly dependent on each other. This can lead to:

✅ Separation Anxiety – Puppies may panic when apart, leading to excessive crying, barking, and destructive behavior.
✅ Fearfulness – Some puppies become overly timid and struggle to adapt to new experiences.
✅ Aggression – Littermates can develop resource guarding or even become competitive with each other.
✅ Delayed Training Progress – Puppies often distract each other, making training and socialization more difficult.
✅ Weaker Bond with Humans – When puppies rely on each other for comfort, they may struggle to form a strong bond with their owner.

What Does Littermate Syndrome Look Like?

Puppies with littermate syndrome often:

🔹 Show extreme distress when separated from each other.
🔹 Ignore their owners in favor of their sibling.
🔹 Struggle with leash training or commands because they focus on each other instead.
🔹 Develop anxiety or fearfulness in new environments.
🔹 Exhibit increased aggression toward each other or other dogs.

If these behaviors aren’t addressed early, they can become long-term issues that require extensive training to correct.

Can You Raise Two Puppies Successfully?

Yes—but it requires dedicated training and structure. If you’re committed to bringing home two puppies, here’s how to set them up for success:

1️⃣ Create Separate Spaces: Each puppy should have their own crate, sleeping area, and feeding station to prevent over-dependence.

2️⃣ Train Individually: Work with each puppy separately to ensure they bond with you, not just each other.

3️⃣ Socialize Separately: Take them on separate outings and introduce them to new people and experiences individually.

4️⃣ Establish Independence: Encourage solo play and alone time so each puppy learns to be confident on their own.

5️⃣ Work with a Trainer: Professional guidance can be invaluable, especially if behavioral issues arise.

At Stokeshire, we’ve successfully raised puppies close in age by following these steps. With time, patience, and the right approach, it is possible to raise littermates who grow into confident, well-adjusted dogs.

What If You Already Have Two Puppies?

If you’re already noticing signs of littermate syndrome, don’t worry—it’s never too late to make adjustments. Start by gradually increasing time apart, working on individual training sessions, and ensuring each puppy has its own safe space. In some cases, professional training may be necessary to correct more severe behavioral issues.

Thinking About Adding Another Puppy?

If you love the idea of having multiple dogs, consider waiting at least a year before bringing home a second puppy. This allows your first dog to mature, establish routines, and receive the training they need to set a great example for a new sibling.

It’s also important to think about the financial and time commitments of having two dogs. Double the food, vet care, training, and daily exercise can add up quickly!

We want every Stokeshire puppy to have the best possible start in life, and we’re here to support you in making the right choice for your family.
